"This other guy said (to the fan holding the knife), 'You don't need to do that' and said, 'F*** off' to me and my pal. We ran like anything.

"But that's what I mean about the stupidity of sectarianism - I could have got a slash on my face for wearing a scarf. It was the other Rangers fan who stepped in and stopped me from getting slashed.

Tommy and Terry told the other housemates that football trouble was a problem, mostly in England.

But Mancunian and Manchester United fan Terry then claimed he had some horrible experiences with both sets of the Old Firm.

He said he'd seen Rangers fans vomiting and urinating when they were in Manchester for the UEFA Cup final last May. He also recalled going to a Man Utd-Gers game as a kid and Gers fans were "all over the place causing trouble".

And Terry insisted Celtic fans' behaviour is just as bad.

He spoke about the day of Bryan Robson's testimonial in 1990.

Terry said: "I got on a bus into town at 10am... Celtic fans came on totally steaming, waving tricolours and singing about Michael Fagan and the Queen."
